JACK.

Application filed October 4, 1920. Serial No. 414,501.

To all whom it may concern:

- Be it known that I, JOSEPH H. Porn, a

citizen of the United States, residing at Hamilton, in the county of Essex and State of Massachusetts, have invented certain Improvements in Jacks, of which the following description, in connection with the ac companying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. The present invention relates to worksupports, such as jacks used for supporting shoes during certain steps in their manufacture, as when portions are attached by nailing or tacking. More particularly the invention is applicable to counter-attaching machines. There is an apparatus of this character, designed to nail molded counters to the soles of turn shoes before the turning operation, which is a modification of the well-known lightning heeler, and is described in the Letters Patent in my name, dated Sept. 19, 1922, No. 1,429,694. To support the counter in positionfor nailing, the die-block of the machine is provided upon its under side with counter-supporting block, against which the heel-seat of the shoe operated upon ispressed duringthe nailing of the counter. In attaching high counters, the travel ofthe cross-head carrying the jack may not be suflicient to remove Y the upper edge of the counter below the supporting block, and this interfereswithi the drawing out of the jack to remove the work.

An object of the invention is to provide a jack which will permit such operations upon the work to be performed without interference. In the attainment of this and similar objects, my improved jack may be mounted upon the usual support, which is movable with reference to the nailing or operating mechanism and to the carrier for the counter or other shoe-portion to allow the'work to be jacked, nailed and unjacked, and is also movable upon said support, there being in this travel a movement-limiting means or stop co-operating with the jack and a movable member co-operating with the movement-limiting means to vary its position. In this combination, with the jack freed from the limiting means, the

. former may be moved away from the nailing mechanism, so that it may be shifted with its support to remove the work without contact with the counter-supporting block.

Upon the other hand, when the limiting means co-operateswith the jack, said jack is held against movement for the nailing operation. In itsnormal-position, when re-v leased from the limitingmeanathe jack is preferably held yieldablyfas by a, spring interposed'between it and the jack-support.

The normal relation between the limiting means and the co-operatmg jack surface may illustrated saidv surface as-providedfiby a collar threaded upon the jack. I prefer tofeffect the movement of the support by connection to a member engaging the Work,

as a toe rest mounted upon the jack-support and joined to the stop; andto allow the :it is to be understood that its application is not so limited, but that it may be em-* ployed wherever it is of, utility for the support of work. a

In the accompanying drawing? illustrating one of severalembodiments of my invention,

attaching machine including my improved jack; and a Fig; 2 is an enlarged side elevation of the jack with the directly co-operating parts Fig. 1 is a front elevation of a counterof the machine, portions being broken away. a

The numeral 10 designates the frame of a lightningfheeling machine arranged for counter attaching, this havingv extending horizontally across it the usual die-block 12.

Above this is mountedto reciprocate the top girt 14;, carrying the drivers 16, while below i the die-block, and movable toward and from it, is the cross-head 18 from which rises the jack J. Secured to the under side of the die-block, in vertical alinement with its nail- I receiving openings and having corresponding openings, is a block 20, 'of such form as to. properly support a counter G placed about it. Fixed to the lower surface of the die-block, adjacent to the counter-block,

jacked shoe is brought into co-operation 65 .be variable, and for this purpose I have I with'it. A back gage 24, arran ed a the rear of the jack for engagement with the counter portion of the shoe, positions it correctly below,v the counter-block for a the nailing operation.

The jack J includes a base or support 26,

mounted to slide in'ways upon the cross head from front to rear, into an operating" position beneath the block 20,0r into a work-applying and removing position in homer said 'blo'fck. j From the rear of the base rises a tubular standard 28, 1n which is guided for-vertical movement a jackpost 30,- at the top of which is mounted a "lastbed 32, withits pin 34L arranged to receive a last, illustrated at L. Threaded through the side of the standard 28 is a screw 86, having are'ducedend entering a vertical slot 38 the jack-post, and preventing its rotation, while permitting its vlongithdinal movement. The jack-post. 1s

urged upwardly in the direction of the cbunterisuppo'rtingblock 20 a helical springl0 situated between the base and the lower endo'f the jack-post, it preferably ce'ssity'for employing an unduly long spring,

its lower extremity may rest upon a spacing melee, resting at its bottom upon the base. Projectingslaterally from this rod is a pin 4A entering a slot L6 in the jackpost, the contact of the lower end-oi the slot with the pin limitingthe upward movein'e'nt of the jack-post by the spring. A

p'ortion of the jack-post is threaded at 48 to receive a contact member," preferably 7,

consisting of an internally threaded collar 50. Pivote'd upon a strap 52, secured about the standard 28, and having an enlarged angular end :54 arranged to enter between the top of the'st'andard and the collar50, is

'a st'opdev'er 56; ."Contact bf the collar with vthe'su pper surface of the'enla rgement 54: will hold the jack-post and work carried thereby I against downward movenfent, while the heel-seat of the jacked shoe is being pressed against the counter and its supporting b'lock'20,an'diwhile said counter, is being nailedto theshoe, *Removal of the portion 54c of t Pi"r'om beneath the collar 1 leaves the iac'k-pbstand work free to be lowered froin theblock 20 against the re-la tivly si nall resisting force of the springAO.

At thefront of the base 26'rises a bracket upon-which is pivoted, at 60, a member f ttor engag ing the work, this being shown as consistingofthe customary toe -rest. 62.

Depending from the bottom bf the toe-rest, below its pivot 60, is astud'FG l, and secured 6a to the side of the stud by a screw 66 passing through an arcuate slates is a link 70, the opposite end of which is articulated at 72 to the lower extremity of the stop-lever 56. The'charact'er' of the connection'is such that, when the upper end of the toe-rest is drawn out to remove it from beneath the jacked shoe, this will not only slide the base 26 in its ways to carry the jack and shoe away from the nailing mechanism to enable the workto be removechbut will also swing the st0p-lever upon its pivot to carry the enlargement 54 from beneath the collar 50. The" slot-and-screw connection 66, ,68, included in the, connections between the toerest and stop-lever,- furnishes an adjustv ment permittingthe angle otthe toe-rest for cooperation with the work toibe varied to adapt it to contact properly with lasted shoes of 'differentsizes. 26 and a portion of the connections between thetoe-rest and stop-lever,as the pivot72,

extends a'tension spring 74:, the effect jot which is to hold the toe-rest in the operating position, and the'end'ofthe stop-lever beneath the collar uponv the jack-post.

In using a counter-attaching machine equipped with my improved jack, the op of the cross-head 18. T-hatis, whenv the c1'oss headis-lowered after the attachment of the counter, the upper edge of "said Between the base ice counter will still,,project above the bottom ,ol the block 20. The support is then; pushed in until the reariotth'e shoe contacts with the gage 24-, the rest 62 at this time being beneath the toe of the jacked shoe, andthe end 54 of the stop beneath and in close proximity to the collar 50, the relation of which to the upper surface of this stop may bevarie'd by turning it on its .thread. This adjustment may bearranged to give almost immediatecontact between the stop elements during the nailing operation, while leaving room between said elements to permit them to bebrought into. co-operation. The work thus positioned, the operator starts; themachinej in action, the, cross-head rising to.

clampthe heel-seat of the shoe against the counter upon its-block, and the, drivers descending to force through the counter into the heel-seatof thetshoe the nails or tacks which have previously been supplied by the usual loading mechanism to the openings in the die-block and counter-block. The

attaching of the counter havingbeen coinpl'e'ted and the machine stopped at theend ofits cycle, the operator, grasping ,the, up-

per portion of the toe-rest with one hand,

draws it forward. As this isdone, the toerest swings from beneaththe'shoe to 'freeit, and moves the stop-portion 54: of the lever 56 outwardlyfrom the jack-post, so that it clears the collar 50. Now the operator, by placing his free hand upon the shoe preparatory to removing it from the jack-post, slightly depresses the released post against the elevating eflect of the spring 40; This lowers the post and shoe sufiiciently tocarry the upper edge of the attached counter be low the bottom of the 'block20, so that said counter is free to move past the block. The jack-support I is now drawn forward, the lasted shoe removed from the post, and the machine is ready for'the succeeding operation, the spring'74 upon therelease of the toe-rest by the operator carrying said rest to its normal shoe-supportingposition, and

the stop-portion 54 into proximity with the jack-post beneath the collar 50. I
